Black galaxy

Black galaxy is a fine to medium-grained black gabbro quarried in the Chimakurthy region of Andhra Pradesh, India, distinguished by its dense matrix and scattered golden-yellow broncite scales that produce a distinctive glitter under light. The stone registers negligible porosity and near-zero absorption, making it highly resistant to staining, etching, and chemical penetration. Petrographically classified as gabbro under European Standard EN 12440, it is marketed as granite in the United States and China. Density and hardness place it among the most durable dimension stones available for commercial surfacing.

The material originates from the Ongole belt, where geological conditions produced an exceptionally uniform black groundmass with consistent broncite distribution. Standard slabs are typically finished polished, though honed or leathered surfaces are common alternatives for specialist applications. The fine grain structure allows precise edge profiling and intricate cut-outs without chipping or breakout. Colour consistency runs deep through the block, reducing batch-matching concerns on large installations. Typical quarry yield favours large-format extraction, supporting gangsaw-size production for international shipment.

Primary buyers include hotel developers, luxury residential contractors, and commercial fit-out specialists specifying premium wet-bar, reception desk, and kitchen counter surfaces. The stone's etch resistance suits high-traffic food service environments where acidic spillage is routine. Importers should confirm current block availability, standard slab thicknesses offered, and whether surface finishing is performed at origin or left to destination fabrication. FOB Chennai or Visakhapatnam are typical export channels for Andhra Pradesh material.

Hari Prasad Exports operates from Chimakurthy in the Ongole district of Andhra Pradesh, placing it within the heart of India's most productive Black Galaxy granite quarrying corridor. The supplier holds a harbor-tier trust designation on the platform, with a response rate currently showing 0.00 percent and no recorded average response hours. Buyers should interpret this as an unverified communication pattern and plan contact attempts accordingly, allowing extra time for initial quotation and sample requests. The listing provides no stated production capacity, workforce scale, or installed machinery base.

The company profile contains no declared certifications, no named clientele, and no explicit years in operation. What is verifiable is the supplier's geographic proximity to active Black Galaxy quarries, which reduces inland transport costs and block-handling risk. The description emphasises petrographic accuracy and international market terminology, suggesting some familiarity with European and American import requirements. Direct inquiry should seek confirmation of quarry ownership versus trading relationships, available finishing equipment, and quality control protocols for broncite distribution consistency.
